“…In dry friction without application, the deformations of the (COTS) with a friction coefficient f = 0.12 are significantly large, which can lead to significant loads on the tool, the emergence of high adhesive bonds and deterioration of the processed surface and high roughness. The use of sulfofresol with a coefficient of friction f = 0.09, the deformation forces in the processing zone are reduced by 1.5 times [7,8,9].…”

The article discusses the effect of epilamated coatings during mandrelling. The picture of the change in contact stresses in the DEFORM-3D system is presented. It was established that a decrease in the coefficient of friction from 0.9 to 0.6 leads to a decrease in the number of foci and areas of contact stresses, as well as temperature analysis showed that a decrease in the friction forces reduces heat transfer in the cutting zone by about 40 ° C.

“…The structure of the vibrational mechanical-chemical coating, as seen from the spectrogram and the section, has a nonporous structure and a sharp boundary between the metal and the coating, which explains its increased corrosion properties and is a distinguishing feature of VMCZC and an undoubted advantage over galvanic coatings.

The results of investigations of zinc coatings obtained on the surface of metals in the process of mechanochemical synthesis realized in conditions of vibro-wave technological systems (VTS) are presented. The features of the morphology of the coating structure are revealed, which activates the role of indents in the formation of free-moving vibrations under the influence of low-frequency oscillations, and its influence on increasing the operational properties of the surface layer of the parts. The advantages of this method of applying zinc coatings in comparison with traditional methods are shown.

The article discusses the issues of increasing the efficiency of using nanocoatings of the working surfaces of a tool operating at relatively low cutting speeds. A theoretical and experimental approach is proposed, which is based on a model of the interaction of the internal three-dimensional state of the epilame layer, a two-dimensional material film and the material line closing it. An analysis of the state and shape of a liquid layer on a flat surface is given under the assumption that Young's equation is valid, which connects the contact angle with the values of surface stresses. Dependencies and a technique are given that allow you to control the behavior of an epilame drop on the surface of the cutting element. It was found that when thin-film coatings are applied from epilame solutions, a film is created on the surface of the instrument, which significantly changes the energy properties of the surface. It is shown that during the study of oil absorption of epilamated and unepilamated surfaces, as well as the study of the behavior of oil, the greatest retention of oil is observed during intermittent epilamated, presented in the form of large drops, the area of which depends on the area of unepilamated areas. It is recommended to carry out the following experimental research technique, which is associated with obtaining the initial parameters for determining the geometric parameters of a drop of the material under study on a flat surface. The radius of the projection of the drop onto the substrate, the profile of the drop when scanning the side view and then taking into account that the drop is a figure of rotation are determined, taking into account the previous data, its volume, the value of the wetting angle and the height of the drop are determined.
